From James Croll 15 February 1869
Edinburgh.
Feby 15th 1869.
Dear Sir,
I am much obliged to you for the copy of Scientific Opinion you sent me containing an abstract of Canon Moseley’s admirable paper on the motion of glaciers1
I have a curious incident to tell you, regarding the matter. The reading of the abstract thoroughly convinced me that the generally received theory of glacier motion, which I believe is that of Tyndall’s,2 must be given up and that some other explanation must be sought. Strange to say, this conviction had hardly got time to settle down, if I may so express myself, before, what I fully believe to be the true cause suggested itself. The cause is so simple, so beautiful, and obvious that I wonder that it should have escaped observation so long.
I have drawn up a short account of the matter and have sent it to the Phil. Mag I have requested Dr Francis to send me two copies of proof and when they come to hand I shall send you one3
I am | Yours very truly | James Croll
Charles Darwin Esq MA FRS
